The main thing that i changed in this class was it use to be extends Fragment to extends ListFragment i believe this is creating the error although not sure how?
package com.TIPA.uips;
import com.TIPA.uips.R;
import android.os.Bundle;
import android.support.v4.app.ListFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.content.Context;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
public class FriendsList extends ListFragment {
public class MyListAdapter extends ArrayAdapter<String> {
Context myContext;
public MyListAdapter(Context context, int textViewResourceId,
String[] objects) {
super(context, textViewResourceId, objects);
myContext = context;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
//return super.getView(position, convertView, parent);
LayoutInflater inflater =
(LayoutInflater)myContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row=inflater.inflate(R.layout.row, parent, false);
TextView label=(TextView)row.findViewById(R.id.carrottop);
label.setText(month[position]);
ImageView icon=(ImageView)row.findViewById(R.id.dp);
//Customize your icon here
icon.setImageResource(R.drawable.dp);
return row;
}
}
String[] month ={
"^Smithy",
"^Kreso",
"^Chen",
"^Dave"
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/*
ListAdapter myListAdapter = new ArrayAdapter<String>(
getActivity(),
android.R.layout.simple_list_item_1,
month);
setListAdapter(myListAdapter);
*/
MyListAdapter myListAdapter =
new MyListAdapter(getActivity(), R.layout.row, month);
setListAdapter(myListAdapter);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.friends_list, container, false);
}
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
Toast.makeText(
getActivity(),
getListView().getItemAtPosition(position).toString(),
Toast.LENGTH_LONG).show();
}
}
This here is the adapter to allow the fragments to return the values of each class believing it is not allowing it.
package com.TIPA.uips;
import com.TIPA.uips.NewsFeed;
import com.TIPA.uips.Chat;
import com.TIPA.uips.FriendsList;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
public class TabsPagerAdapter extends FragmentPagerAdapter {
public TabsPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int index) {
switch (index) {
case 0:
// Top Rated fragment activity
return new NewsFeed();
case 1:
// Games fragment activity
return new Chat();
case 2:
// Movies fragment activity
return new FriendsList();
}
return null;
}
@Override
public int getCount() {
// get item count - equal to number of tabs
return 3;
}
}
Cheers
UPDATE:
New error occuring when implemented listview in xml with id/list.
